Technical Field

The utility model relates to the technical field of oil fume purifiers, in particular to a self-cleaning oil fume purifier.

Background Art

Kitchen fumes and factory smoke problems will directly affect people's health. If they are not filtered and directly discharged outdoors, they will cause great harm to the air quality.
